Smaller than asteroids and comets are meteoroids, which are fragments of rock or metal that range in size from a grain of dust to a few meters across. When these meteoroids enter Earth's atmosphere and produce a visible streak of light, they are referred to as meteors. If they survive the passage through the atmosphere and land on the Earth's surface, they are called meteorites.
